Belgrade, September 11 (Beta) - Serbian Interior Minister Dusan Mihajlovic condemned Tuesday's suicide attacks on the US. "Terrorism as the world's evil has shown its true face", Mihajlovic said.

"What happened in the world's most developed country, with its nearly infallible defense system, serves as a warning to the entire world that we all have to unite in the struggle against terrorism", Mihajlovic said.

According to Mihajlovic, it will be difficult to establish who is behind this violent crime which claimed so many lives and which will have far-reaching effects on international politics and international security.

The Serbian Interior Minister said that the Serbian government and police "have taken appropriate steps to step up security at facilities that could be attacked in Serbia".

Mihajlovic added that the police would continue to monitor further developments in connection with Tuesday's attacks on the US.
